Primary Outcome Measures:
  • Safety [ Time Frame: within 1 week (0-7 days) following each vaccinations ] [ Designated as safety issue: Yes ]

    Safety and Tolerability assessed by cohort and product received measured by:

    • Number of vaccine-related SAEs
    • Proportion of subjects AEs leading to discontinuation of product or study
    • Proportion of subjects with >= Grade 2 local reactogenicity events
    • Average duration of local reactogenicity
    • Proportion of subjects with Grade 2 or greater systemic reactogenicity
    • Average duration of systemic reactogenicity
    • Number of unsolicited AEs within four weeks after each vaccination
    • Maximum severity per volunteer
    • Proportion of AEs related to vaccine

Secondary Outcome Measures:
  • immunogenicity [ Time Frame: 28, 56 and 84 days following initial vaccination ] [ Designated as safety issue: No ]
    • Determination of a humoral immune response to whole cell antigen as determined by ELISA of sera collected on Day 0, 28, 56, and 84.
